A $T$ shaped uniform density object with dimensions shown in the figure is lying on a smooth floor. A force $\vec{F}$ is applied at the point $P$ parallel to $AB$ such that the object has only the translational motion without rotation. Find the location of $P$ with respect to $C$ .

Options:

Answer:

Solution:

It is a case of translation motion without rotation. The force should act at the centre of mass

$Y_{cm} = \frac{(m \times 2 l) + (2 m \times l)}{m + 2 m} = \frac{4 l}{3}$

( considering point $C$ as origin )
